I have the 1GHz Ti Book, 15", 1GB PC133 memory, 60GB 4200 RPM drive, Tiger, and it's awesome. Battery is basically dead (10 min). I do typical web/email stuff. I also do some music recording and it works fine. Watching video is difficult on youtube or nbc.com, though. I need to upgrade to Leopard as I want to start doing Web Development using Rapid Weaver. The new version of Rapid Weaver requires Leopard. So, while I'm planning on purchasing a new machine soon, I wonder if it's worth spending the money to: 1) buy Leopard for my TiBook (are there performance issues?) 2) buy a 7200RPM drive (for performance) in order to run Rapid Weaver 4.0 or not. Thoughts?
